JP 2003-89525 A

  By the way, although the timepiece is made of glass or metal, various materials such as leather, metal, cloth, and rubber exist in a band for wearing on the arm.

  Applicants have developed a watch made of various materials to apply photocatalytic technology.

  However, titanium dioxide used as a photocatalytic substance is easily removed from the fixing surface of the substance to be fixed, and it is difficult to maintain the effect of the photocatalyst. In particular, in a watch that is suspended from a wristwatch or a bag, the photocatalytic substance is likely to fall off because it contacts various parts during use.

  In order to fix titanium dioxide to a substance, various binders may be mixed in a solution that is applied, sprayed and immersed, but the affinity with titanium dioxide is poor, and in particular, watches have leather, cloth on the surface. In many cases, various materials such as metal and glass are used, and there is no binder that stably fixes titanium dioxide to all these materials.

  Therefore, the applicant conducted experiments based on trial and error using various fixing agents in order to stably form titanium dioxide as a photocatalytic substance on the surface of the watch. As a result, it was possible to stably form a photocatalyst layer that is difficult to peel off on the surface of a watch made of various substances. That is, an object of the present invention is to provide a photocatalyst layer reliably and stably in a timepiece formed of various materials.

  In order to achieve the above object, a device according to claim 1 is a timepiece having a timepiece main body having a time display portion and a mounting portion attached to the timepiece main body so that the timepiece main body can be attached to any part. The photocatalyst layer containing titanium dioxide and polyester is provided on the surface of the watch body or the mounting portion.

  The invention according to claim 2 is the timepiece according to claim 1, wherein a portion where the watch body is mounted is an arm, and the mounting portion is a watch band attached to the watch body.

  The invention according to claim 3 is a timepiece according to claim 1, wherein a part to which the watch body is attached is a suspended part such as a clothes or a bag suspension, and the attachment part is attached to the watch body. It is a member.

  The invention according to claim 4 is the timepiece according to any one of claims 1 to 3, wherein the mounting portion is formed using any material of leather, metal, cloth, rubber, and the photocatalyst layer is It is made of a material and fixed to all or part of the surface of the mounting portion.

  The invention according to claim 5 is the timepiece according to any one of claims 1 to 4, wherein the watch body is made of any material of plastic, glass, or metal, and the watch body is provided on the outer surface thereof. A material surface of the material is provided, and the photocatalyst layer is fixed to all or part of the surface of the material surface.

  The invention according to claim 6 is the timepiece according to any one of claims 1 to 5, wherein the photocatalyst layer is immersed in a liquid containing titanium dioxide and polyester, and the timepiece and / or the mounting portion is immersed, or titanium dioxide. And a liquid containing polyester and polyester are applied or sprayed on the watch body and / or the mounting part, and the liquid is dried and fixed on the watch body and / or the mounting part.

  The photocatalyst has the effect of improving the antifouling, deodorizing, bactericidal and antifogging properties of the substance. As a photocatalyst material with good photostability, there is titanium dioxide, and a photocatalyst material mainly composed of titanium dioxide is widely used. In the present invention, such photocatalyst material is fixed to the material surface with high adhesion, and is mixed with polyester to improve the affinity with the material.

That is, according to an experiment conducted by the present inventors, titanium dioxide, polyester, and additives are mixed with water as a liquid to produce the following working fluid, which is then used as leather, metal as a watch member. After fixing the film by immersing it in cloth, rubber, plastic, or glass, it was confirmed that good fixability was confirmed in any substance.

  1 and 2 show a wristwatch according to the present embodiment. This wristwatch is provided with a watch band 2 on a watch body 1 provided with a time display unit 3 and a band mounting part 6 provided as a pair on the watch side 4 of the watch body 1. The watch body 1 includes a watch glass 3 made of glass and transparent plastic for viewing through the time display unit. Further, the watch side 4 portion of the watch body 1 is made of metal, and the watch band 2 as a mounting portion is made of a material such as leather or artificial leather.

  The watch glass 3 used in the time display unit can use the glass, transparent plastic, or the like described above, but it is preferable to use tempered glass in consideration of the properties of the watch used permanently. The watch side 4 may be made of metal such as stainless steel or plastic.

  The formation of the photocatalyst layer 5 on the wristwatch thus formed is fixed by immersing the entire wristwatch in a working fluid comprising the above components, pulling it up and drying it. As shown in FIG. 2, a photocatalyst layer 5 is formed in a thin film on the surface of the watch body 1 and the watch band 2 soaked and dried in the processing liquid in this manner, and this portion is attached by absorbing ultraviolet rays or the like. The watch band 2 and the watch body 1 as a part exhibit effects such as antifouling, deodorization, sterilization effect, and time display part antifogging effect. That is, sweat, dirt, etc. are likely to occur on the arm to which the watch body 1 is attached, and dirt and odors are easily absorbed from the skin and clothes in the watch body 1 and the watch band 2 in contact with the watch body 1 and the bacteria from the dirt. May occur. In this regard, according to the wristwatch according to the present embodiment, the action of the photocatalyst layer 5 can exert effects such as antifouling and sterilization in the watch body 1 and the watch band 2.

  However, the present invention is not limited to the method of immersing the entire wristwatch in such a working liquid, and the working liquid can be fixed by applying (coating) with a brush or spraying with a spray. In the case where the working fluid is applied or sprayed and fixed, unlike the case where the photocatalyst layer 5 is formed on the entire wristwatch as in the case of the immersion described above, a portion of the wristwatch is masked with a tape or the like, and the working fluid is watched. The photocatalyst layer 5 can also be formed at a desired position.

  As for drying, even if it is leather, metal, cloth, etc., which is a constituent material of the wristwatch, if it is naturally dried, it will be heated by heat of about 40 ° C. for about 30 minutes to 1 hour after immersion, coating and spraying. In the case of drying, the photocatalyst layer 5 can be formed by a drying operation of about 20 to 40 minutes. In addition, when performing thermal drying, sodium ions in the glass diffuse into the photocatalyst layer and the photocatalytic activity is lowered. 5 is preferably formed.

  Embodiments of the present invention will be described below with reference to the drawings.
